O-1 vs ESTA
ESTA is an electronic authorisation for short trips of up to 90 days, with no extension and no right to work; the O-1 is a work visa for people who show extraordinary ability. Chile is the only Latin American country in the Visa Waiver Program, which makes exploratory visits easy. But to actually work in the United States, even on a single project, you need an O-1 petition.
These two categories differ on 8 of 10 criteria. The full table is below, but if you only have a minute, these are the differences that decide a case.
